Coordination state of B and Al in low-alkali alumoborosilicate glass

The structure of aluminoborosilicate glasses has been studied. It was found that the coordination states of boron and aluminum in glasses can vary depending on the composition, which significantly affects the properties of glazed glasses. Significant discrepancies between the experimental and calculated LTEC values ??of such glasses were found, which is explained by the change in the proportion of boron in the fourfold coordination and the appearance of aluminum in the sixfold coordination. Given these data, it is possible to predict the physicochemical properties of glazed glasses. Tab. 1, ill. 2, bibliography: 10 titles.
